Kubernetes Misconfiguration: NamespaceLifecycle Enforcement Disabled

YAML

Abstract

Kubernetes API 伺服器中的 NamespaceLifecycle 准入控制器已停用。

Explanation

若刪除 Kubernetes 命名空間，將會移除該命名空間中的所有物件，包括 Pod 和服務在內。NamespaceLifecycle 准入控制器使用兩種方式維護 Kubernetes 系統的完整性。第一種方式是防止在不存在的名稱空間或正在終止的名稱空間中建立物件。第二種方式是防止系統保留的命名空間 (其包含 Kubernetes 關鍵服務) 被刪除。

NamespaceLifecycle 准入控制器預設為啟用，但啟動 Kubernetes API 伺服器的指令已利用 --disable-admission-plugin 旗標將其停用。

範例 1：以下組態將啟動 Kubernetes API 伺服器。如果 NamespaceLifecycle 包含在 --disable-admission-plugins 旗標中，就會停用 NamespaceLifecycle 准入控制器。


...
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --disable-admission-plugins=...,NamespaceLifecycle,...
    ...
